I have this irrational fear of weed particles being on things, because I had a terrible experience one time and got depersonalization and it lasted for 2 years. It was Hell, and I never want to go thru something like that again. Anyway, My brother likes weed and he does it occasionally and I don't want to touch anything he touches because I am worried I will be touching weed particles. And please don't tell me there aren't weed particles anywhere around my house because if someone goes out and smokes weed and comes back to a house, there are particles! Anyway, just worried I will touch some without knowing and put my fingers in my mouth or something and ingest weed....and I cant keep washing my hands, they are bleeding. help?
